' To all 'zohom it may concern:

Be it known that we, ERIC S. SANDGREN, a subject of the King of Sweden, and CHARLES F. Case, a citizenof the United States of America, residing at Detroit, in

.the county of lVayne and State of Michigan, have invented certain new and useful Improvements in l\l0l0r-Vehiclcs, of which.-

thefollowin is a specification, rejerence being had tierein to .the accompanying drawings.

In the construction of automobile trucks and vehicles for commercial uses it isdesirable that the power plants be so situated as to be easily removed for repair-or be inter changedwith others where greater or less horse power is desired for different purposes. v

This invention relates to automobiles and more especially to an arrangement of 'the power plants thereof whereby they may be readily removed when the vehicles have" een repaired or be interchanged for other plants.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a view in side elevation of a portion of the chassis of an automobile with a power plant thereon that embodies features of the nvention; Fig. 2 is a view in front elevation thereof;

' Fig. 3 is a view in detail of the forward cross member.

As hcreinindicated, the side members 1 of a chassis of usual type are secured atan interval from their forward ends by a cross bar 2; A cross member 3, preferably forged or cast in a single piece h s its ends 4 se-' cured as by bolts 5 betwe n the flanges of the channel comprising the side members of the chassis. A pair of forwardly extending brackets 6, suitably ribbed and flanged for strength and lightness are formed on the outer face of the cross member and a be. ring 7 is centrally disposed thereon between the brackets in advance of an opening in the body of the cross member, by arms 8 spanning the opening and integrally formed on the member.

A motor 9 that is herein illustrated as of, the double opposed type but which maybe of any preferred form having a main shaft arrangedlongitudinally of the chassis has a forward port-ion of its crank case secured against the rear face of the forward cross members by bolts '10, or the like with B. ta-rting shaft 11 in aline'ment with the central bearing? ofthe member in. which it is journaled. A rearwardly projecting portion- 12 of the casing that is referably formed integrally. thereon is faced or otherwise fitted to receive the end sion mechanism case 13 that is secured there'- to by bolts 14 or the like passing through abutting flanges or lugs on the meetin parts. A circular boss 15 on the-end of the transmission shaft casing is receive the bearing of a transmission shaft .16 extending therethrou h and is itself su orted in a suitable bloc 17 by a clip or 8- olt l8 embracing the boss and passing through the cross bar 2 of the phas'sison which the block is placed. lubricator of an preferred form-suitable for the work to be done is mounted on the motor.- As herein indicated the casing 19 of the lubricator is bolted or. otherwise properly secured to the'under'side' of the motor casing.

A radiator 20 is supported on the forwardly extending brackets of the cross m'emher and bridgesthe starting shaft and hearing therefor The central portion adjacent the bearing is cut away an in the opening thus formed a magneto '21 is cross member and coupled directly to the motor through 'a suitable coupling 22 or other preferred form of driving connection. A mufiler 23 is suspended below the radiator by pipes24 leading from the exhaust openings of the cylinders. Water connection with the-radiator is made throu h suitable fittings 25 on the cylinder and ra iator, cou-' pled by hose 26 in the usual manner. Rock shafts 27 that project be 0nd the transmis, .sion casing'may be detacliably coupled with any preferred form of control levers onthe truck body to give the usual motor control. Eye-bolts 28 maybe added for'conveniently applying a chainbridle 29 for lifting the plant from thechassis. I

By this method of construction a complete power plantis obtained'that forms a. bodily removable'unit supported on three points on =th forward portion of the chassis in such manner that it can be readily removed by taking out the retaining bolts- 21i." these places and applying thebrldle' r like-part as indicated. As the radiQtOr 'Isthe only portion of the mechanism that extends above A eoaronarrou or of a transmisplaced on the 'pertured to the chassis the operators platform can be, removably'secured over the plant thus leavnism for propelling the vehicle is bodily removable with little trouble.

l pair of side members permanently connect-- Obviously, ,changes in the details of 'construction 'may be madewithout departing from the spirit of the invention and We do not care to limit ourselves to any particular formor arrangement of parts.

We claim as our invention:

1. The combination of a chassishaving a pair of side members permanently connect-- ed at an interval from their 'forward' ends by a cross bar, with a cross member adapted to be detachably securedto' the forward ends ofthe chassis side'members and having a central 'earing, a motor secured to'the rear side of the cross members, a starting shaft for the motorzextending through said hearing in the cross member, a transmission casing secured to'the motor with its free end detachably and rotatably mounted on the cross bar, a radiator for the motor supported on the member andian electric generator for the ignition system of themotor on the cross member. 7

2. The combination of a' chassis having a ed at an intervalifr'om their forward .ends by a cross bar, .of a cross member adapted to be secured detachably to the forward ends of the chassis side members, a bearing on the cross member, a motor secured to the rear i side of the cross member, a. starting shaft for the motor journaled inthe cross member bearing, a transmission casing secured to the rear side of the motor with its free end detachably and rotatably secured on the cross bar, member, an electric generator for the ignition system of the motor mounted on the cross member,and a mufiler for the motor suspended from the motor.

3. The combination of a chassis having a pair of side members permanently secured at an interval from their forward ends by a cross bar, with a cross member adapted to be detachably secured to the forward ends of the side members, a motor secured to the rear face of thesaid member and provided with a transmission casing whose free endis detachably supported on the cross bar, a starting shaft for the motor rotatably mounted on the cross member, aoradiator supported on the cross member and provided with a lower central-bpenirg, a gen erator for the motor ignition systen secured on the cross 'member within the iadiator opening, and a muffler below the cross member secured to the motor. g
